there is sufficient food for 800 men for 62 days after 56 days 560 man leave the place for how many days will the rest of the food last for the rest of the men
Let each man eat 1 unit of food per day.
Initial quantity of food = 800x62 = 49600 units
Quantity of food used in 56 days = 800x56 = 44800 units
Remaining amount of food = 49600-44800 = 4800 units
Remaining men = 800-560 = 240
So number of days the food will last = 4800/240 = 20 days
